How many valence electrons are in lutetium?
2 valence electrons
Which electrons are responsible for current in a material?
The conduction band electrons. These are valence electrons that become delocalized in conductors and form an "electron gas" that fills the bulk of the conductor and can flow as a fluid in response to electric fields applied across the conductor.
